Description
The CAOS (Centro per Applicazioni sulle Onde gravitazionali e la Sismologia) facility is currently under construction in Perugia, Italy. It will host a short Fabry-Perot cavity to carry out dedicated R&D on seismic attenuation systems for ET, specifically enabling the development of two AdV-like Superattenuators (SAs), a technology that represents the ET reference solution as envisaged in its conceptual design.
Both SAs will be taller than those of AdV+ and they will incorporate new technologies, such as new Magnetic Anti-Springs. However, during the conceptual design phase, we adopted slightly different approaches for the two SAs. The one called BS will be conceptually very similar to the AdV+ SA, whereas the other, named EE, will introduce new concepts and features, including innovative crossbars for seismic filters, a Disk 0, and an active platform with enhanced "feet".
The mechanical design is currently in progress thanks to a collaborative effort between INFN Pisa, INFN Perugia, and UNIPG. Meanwhile, the manufacturing of mechanical components has already begun at Galli & Morelli's workshop.
